Injuries increase the amputee burden at the prosthesis centre: a 2-year retrospective survey of amputees in a low-income setting

The aim of this study is to survey different types of injuries as the cause for prosthesis fitting in the Institute of Physical Medicine and Rehabilitation (IPM&R). This retrospective chart review was conducted at the IPM&R at the Dow University of Health Sciences, from the year 2007 till 2009. We selected all amputees who got enrolled in our institute for prosthesis fitting with major amputations, during the above mentioned period of time. Informed verbal consent was taken from each patient before recording their data at the IPM&R. Anonymity has been maintained. Data for this study was collected through a structured questionnaire, variables included: gender, age, town of origin, cause of amputation, level of amputation, limb involvement (unilateral or bilateral), level and causes of amputations. The data entry and analysis were done on SPSS (Statistical Package of Social Sciences) version 16.0. Of the amputee burden of our study, 55.9% was due to trauma, which is a preventable cause of disability. This is mostly affecting men in the productive age group. New strategies need to be devised in order to alleviate the burden of amputations resulting from preventable injuries.     

A Classroom Tariff-Setting Game

The author outlines a classroom tariff-setting game that allows students to explore the consequences of import tariffs imposed by large countries (countries able to influence world prices). Groups of students represent countries, which are organized into trading pairs. Each group's objective is to maximize welfare by choosing an appropriate ad valorem tariff that may be changed intermittently throughout the game. The game is built on a computable general-equilibrium model, which allows each nation's utility and terms of trade under alternative tariff regimes to be expressed quantitatively. The exercise encourages students to consider terms-of-trade improvements and efficiency losses resulting from large-country tariffs and provides a framework to discuss the Nash equilibrium of a tariff war. The game is a useful supplement to traditional teaching methods.     

Palonosetron versus other 5-HT3 receptor antagonists for prevention of chemotherapy-induced nausea and vomiting in patients with hematologic malignancies treated with emetogenic chemotherapy in a hospital outpatient setting in the United States

Abstract

Objective:

This study evaluated the rate of uncontrolled chemotherapy-induced nausea and vomiting (CINV) after initiating antiemetic prophylaxis with palonosetron versus other 5-HT₃ receptor antagonists (RAs) in patients diagnosed with hematologic malignancies (lymphoma and leukemia) and receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC) in a hospital outpatient setting.

Methods:

Patients aged?≥?18 years and diagnosed with hematologic malignancies initiating HEC or MEC and antiemetic prophylaxis with palonosetron (Group 1) and other 5-HT₃ RAs (Group 2) for the first time in a hospital outpatient setting between 4/1/2007 and 3/31/2009 were identified from the Premier Perspective Database. Within each cycle, CINV events were identified (in the hospital outpatient, inpatient, and emergency room settings) through ICD-9 codes for nausea, vomiting, and/or volume depletion (from each CT administration day 1 until the end of the CT cycle), or use of rescue medications (day 2 until the end of the CT cycle). Negative binomial distribution generalized linear multivariate regression model estimating the CINV event rate on CT, specific CT cycles, and cancer diagnosis (leukemia/lymphoma)-matched groups in the follow-up period (first of 8 cycles or 6 months) was developed.

Results:

Of 971 identified patients, 211 initiated palonosetron (Group 1). Group 1 patients comprised of more females [50.2 vs. 41.4%; p?=?0.0226], Whites [74.4 vs. 70.4%, and Hispanics [7.6 vs. 6.3%; all races p?=?0.0105], received more HEC treatments [89.6 vs. 84.2%; all CT types p?=?0.0129], and had more lymphoma diagnosed patients [89.6 vs. 76.3%; all cancer types p?=?0.0033] at baseline. After controlling for differences in several demographic and clinical variables, the regression model predicted a 20.4% decrease in CINV event rate per CT cycle for Group 1 versus Group 2 patients. Study limitations include potential lack of generalizability, absence of data on certain confounders including alcohol consumption and prior history of motion sickness, potential underestimation of incidence of uncontrolled CINV, and inability to draw conclusions pertaining to cause and effect relationship.

Conclusion:

In this retrospective hospital study, patients with hematologic malignancies treated with HEC or MEC and initiated on antiemetic prophylaxis with palonosetron in the hospital outpatient setting were more likely to experience significantly lower CINV event rates (in the hospital outpatient, inpatient, and emergency room settings) versus patients initiated on other 5-HT₃ RAs.     

Agenda formation and accounting standards setting: lessons from the standards setters

There are many studies on lobbying of accounting standards, but the technical agenda of regulators is taken as ‘given’ and why a particular topic was admitted to the agenda is not investigated. Agenda formation is important as control of the agenda determines which topics get regulated and the form of the regulatory response. A few studies have explored agenda formation across regulatory institutions but are largely silent on the role of individual decision makers and technical staff. However, the standards setters have sought to explain their agenda processes. This paper reviews statements by the members of accounting standards setting agencies about their experiences of agenda formation. It identifies insights gained from standard setters and makes some suggestions for future research.     

Investigating corporate management lobbying in the U.K. accounting standard-setting process: a multi-issue/multi-period approach

A large body of literature examines the motives of corporate managers to lobby accounting standard-setters. In general, studies confine their examination to single episodes of the standard-setting process (e.g., exposure draft). This article extends the literature by adopting a multi-issue/multi-period approach to investigate corporate lobbying of the U.K.'s ASB. The findings suggest that the extent of corporate lobbying, defined on the basis of the frequency with which companies made submissions to all of the publications issued by the ASB over a six-year period, depends on the size of companies, the debt covenant costs they face and whether they are listed on a U.S. stock exchange. Separate analyses, however, involving (a) the frequency of lobbying on income-related issues and (b) the frequency of lobbying on disclosure issues revealed that, while all these three variables explain lobbying on income-related issues, only size is significant in explaining lobbying on disclosure issues. The results also suggest that the debt to equity ratio is an imperfect proxy for debt covenant costs.     

Politics, Processes and the Future of Australian Accounting Standards

The perspective of public interest and interest group theories of regulation is adopted to consider the future of Australian accounting standards following major reforms proposed by the Australian Commonwealth government as part of its 1997 Corporate Law Economic Reform Program (CLERP). Interest groups in the Australian environment are identified. Their lobbying had influenced the initial proposals; and their reactions when the CLERP proposals were published resulted in substantial modifications to the CLERP proposals, which had initially recommendedthat International Accounting Standards (IASs) be adopted as national standards from 1 January 1999.
The role of accounting standards and the structure of standard setting are explored. The political nature of standard setting is illustrated through a review of the CLERP proposals, submissions of various interest groups and the government's responses to them. The central arguments are that key assumptions underlying the CLERP proposals are flawed, and that the CLERP proposals could not achieve the outcomes desired of them.
It seems inevitable, however, that international standards eventually will supplant domestic standards. In the longer term, Australian standard setters seem destined to have a diminished role in the international standard setting arena.     

Marketed tax avoidance: an economic analysis∗

Recent years have witnessed the growth of mass-marketed tax avoidance schemes aimed at the middle (not top) of the income distribution, with significant implications for tax revenue. We examine the consequences for the structure of income tax, and for tax authority anti-avoidance efforts, of tax avoidance of this type. In a model that allows for both demand- and supply-side considerations, we find that: there is an endogenous threshold income below which taxpayers do not avoid, and above which they avoid maximally; the per-dollar price of tax avoidance is decreasing in income under progressive taxation; endogenous adjustments in the price of avoidance make supply less responsive to anti-avoidance activity than thought previously; and avoidance may drive a non-monotone relationship between tax rates and tax revenue. These findings suggest that new approaches to anti-avoidance, beyond legal enforcement, might be needed.
